This research aims at proving the fact that the forms, spaces and many other design concepts of Modernism are much related with the changes of materials, struc-tures, and the way of construction as well as the idealis-tic and aesthestic things through the history of steel, one of the most important materials of the style. The meaning steel has in the modern architecture can be studied in the structure and industrial production system. 1) Steel frame broadened the range of understanding the space and created the new form through the skeleton/skin structure by reinterpreting the existing space fac-tors while it was being adopted to the architecture. Walls could be freed from the traditional function of bear-ing wall and roofs gave the transparancy to the interior by being linked with the glass. Posts lost the function which confines the space in the frame of the grid system and gave the flexibility to the interior due to the economical materials. These changes made the movable partition, screen with various materials and the system furniture which divides the space more important. 2) In the aspect of the industrialized architecture, it be-came the moment that the most of the archtectural com-posing parts were in mass production as they were standarized, high qualified, and generalized by the indus-trial characteristics of steel, and the specialization of structure and cladding, but the neither of the efforts to make the building itself by mass production or to standarize it was fulfilled. The high-tech architecture which borrows its archtectural manifestation from the high technology, however, is consistently paying efforts on such industrialization.

A slide-rail system is widely used in home appliances, furniture, mechanical rigs, and so many other applications; due to its high strength and performance for easy moving heavy objectives. In general, a pair of side slide-rails is set on both sides of a drawer to support and move it. So an unbalanced sliding motion can occur during opening and closing a drawer with pull and push force. To settle this problem, single central slide-rail having three collapsible rail-bodies was firstly proposed in this work. 'H'-beam shaped rail-body was newly designed to have enough bending and twisting strength. The experimental test showed that the proposed rail could be applied to large-size home appliances for easy moving drawer with heavy weight.

The study suggests that to compensate for the variety of inhabitants, flexible housing plans are needed. Furthermore, it proposes the support and infill system for the flexible plan of multi-family housing based on the inhabitants need. The inhabitants' need for the flexible plan of multi-family housing was studied using a survey using models. The survey target was the 100 housewives living in a $126.6m^2$(sold as 45 Pyeong) Apartment in Busan. The characteristics of the respondents were first examined, then to figure out the attitude towards the need for the flexible plan of multi-family housing, the concept and preference for the plan, and the satisfaction level of the current apartment plan were analyzed. To find out the structure of the flexible plan of multi-family housing, the need for the structure, furniture, light, and finishing materials were studied. Lastly, to learn the durability of the construction material, the preferred moving period and the reasons were researched. On the basis of the findings, the support and infill system was suggested.

The aim of this study is to extract the design vocabulary of flexibility from analyzing Steven Holl' architectural works. For this purpose, the four works were selected and the design elements like their concepts, elevations, plans, furnitures, lights, materials, and colors were analyzed. The results of this study are as follows ; First, flexible design method is shown in adaptable space planning by using system of hinged panel and multi-functional furniture of various form. Second, Windows were made a plan of the geometric partition of surface and with clear materials for expanding space to outside. Third, the changing of level and the using of the phenomenological elements like a light color, water, and materials were applied for enhancing the image of the flexible space.

Through the computer simulation of virtual reality techniques, prospective clients can experience the surroundings such as the view, traffic and convenience facilities in advance. Also, consumers can reflect their own tastes in the real apartment Interior construction through their own work in relation to furniture arrangement, color choices, etc. inside the apartments. The virtual model house not only replaces the function of the existing model house but it can also provide some services that could not be provided easily due to some restrictions under real conditions. More, it can provide a precise view of the outside appearance and surrounding environment as well as inside the house, as virtual structures on the computer. Consumers can search for the information through the Web in advance and consumer-satisfaction type of apartments can be built. For this purpose, smooth communications among the designers, server managers, and consumers should be achieved as a prerequisite to the delivery of the necessary information.

The purpose of this research was to grasp the space funtions, the preferred image in bathroom and to find out the plan of bathroom. The subjects of investigation included university students in third decades of which data were obtained by the questionnaire survey method. The major findings were as follows: 1) The space funtions of bathroom were the hygienic activities and the supplementary funtions as resting and health-care. 2) Total and facility image in bathroom take a serious view of a sanitary, a function and following to a mood , a sense of space. 3) The preferred type of bathrooms were identified as the 2-space type. Furthermore, the demands were needed in radiator & pannel heating system, storing furniture and funtional lighting & mirror. According to those results, three types of space plan for bathroom can be suggested and color & forms of design elements can be proposed.

Unlike a typical metal spring, a gas spring uses compressed gas contained in a cylinder and compressed by a piston to exert a force. A common application includes automobiles where gas spring are incorporated into the design of open struts that support the weight of tail gate. They are also used in furniture such as office chairs, and in medical and aerospace applications. The gas spring works by the application of pressurized gas (nitrogen) contained in a cylinder. The internal pressure of the gas spring greatly exceeds atmospheric pressure. This differential in pressure exists at any rod position and generates an outward force on the rod, making the gas spring extend. In this paper, we investigated the dynamic characteristics of a gas spring on an automotive tail gate system.

Recently according to the fashion of well-being, it is increasing that heat recovery ventilator is applied to the apartment housing, But the uniform locations of inlet and outlet in each room may provide better indoor air quality than ununiform locations of inlet and outlet. Proper design of air supply system requires information concerning the gas concentration difference between the ventilation effectiveness at the breathing line. This paper presents models to predict the gas concentration difference and the ventilation effectiveness, based on the two cases with proper number of outlets. As one of the results it is desirable to set the outlet location near the furniture which produce the contamination gas so much.

가구 제품 설계 및 디자인의 과정이 고도로 높은 기술력을 바탕으로 이루어지고 있으며, 국내의 가구 기업체도 우수한 기술력과 높은 품질로 경쟁력을 키우며 다양한 고객의 요구에 대응하여 고객만족을 꾀하여야 한다. 이의 기반이 되는 제품의 품질과 사양은 설계에서 시작되는데 아직 국내의 많은 가구기업들은 설계 및 제작 단계에서 많은 시간과 비용을 낭비하고 있다. 3D Modeling Solution은 설계오류가 적으며 시각적인 설계를 할 수 있어 최소의 인력으로 제품을 설계할 수 있는 장점이 있지만 너무 많은 기능으로 인해 사용자가 쉽게 적용하고 사용하기 어려운 단점을 가지고 있다. 본 연구에서는 Autodesk사의 Inventor와 Microsoft Visual Basic으로 Inventor에서 제공하고 있는 API함수를 이용하여 조립자동화를 위한 조립조건 생성, 조립자동화, 부품 재질변경, 수동조립 그리고 부품의 DB화를 구현하고 Add-ln 기능과 미리보기 기능을 구현하였다. 그리고 Actify사의 SpinFire Professional 프로그램을 이용해서 웹에서 모델링된 가구 부품이나 제품을 볼 수 있게 하였다.
